Making new modules available in an Odoo instance so they can be installed is something that newcomers to Odoo frequently find confusing. But it doesn't have to be, so let's get familiar with that.
Installing additional modules
Finding community modules
There are many Odoo modules available on the internet. The Odoo apps store at apps.odoo.com is a catalog of modules that can be downloaded and installed on your system. Another important resource are the Odoo Community Association (OCA) maintained modules, also available on GitHub at https://github.com/OCA/. The OCA is a non-profit organization created to coordinate community contributions, promoting quality, software best practices, and open source values.
